C# 当存在两个模型（元组）时，如何将视图与相关模型绑定

我在MVC 4中工作，希望在视图中绑定两个使用Tuple的模型，现在我希望从两个不同div中的两个模型中获取值，但我得到以下错误：

here is my Controller code:

        public ActionResult Edit()
        {
            CygnusInternalResponseViewModel result = new CygnusInternalResponseViewModel();
            result = new Logic(CApplicationId, CurrentCompanyId).GetProducts();
            if (result.Success)
                return View(result.Model);

            ProductOrderViewModel objparent = new ProductOrderViewModel();
            List<ProductOrderViewModel> viewmodel = new List<ProductOrderViewModel>();
            viewmodel.Add(objparent);
            return View(viewmodel.AsEnumerable());

          //  return View();

        }

---

创建一个包含两个模型的类，并从控制器中填充它们：

public class FooViewModel
{
 public List<ProductViewModel> Products {get;set;}
 public OrderViewModel Order {get; set;}
}

还请注意，如果其余字段与订单相关，则它将位于

订单

属性中，即：

@Html.LabelFor(m =>m.Order.SubTotal)

---

不能使用

元组来绑定表单控件。使用视图模型。@StephenMuecke我需要两个视图模型，那么我该怎么办？您不需要两个视图模型-您需要一个具有两个属性的视图模型。我已经这样做了，但foreach行上的getting error不包含“Product”的定义，并且没有扩展方法“Product”另一个自解释的错误-您的GET方法没有通过
ProductOrderViewModel
的实例传递给视图-您将
列表传递给视图，因此出现错误。修复您的控制器代码。@foreach line上的获取错误不包含“Product”的定义，也不包含扩展方法“Product”@AhmadCheema它应该是
Model。Products
不是
Model。Product
mind。亲爱的，我已经在Model中编写了产品，所以不能在这里使用额外的s来编写…对吗？亲爱的，现在我在第行中遇到了错误72:@Html.EnumDropDownListFor（m=>m.Area，新错误：Cygnus.Global.ViewModels.ProductOrderViewModel'不包含“Area”的定义and@AhmadCheema只需将其更改为
公共列表产品{get；set；}
到
公共列表产品{get；set；}
